Fa'amatalaga Puupuu:

TND/svc faasologa fuly otometi lava faatonutonu voltage e aofia ai le faafesootai auto transformer, servo afi, otometi pulea matagaluega etcWhen grid voltage le mautu po o suiga uta , otometi sampling pulea matagaluega auina atu se faailo e ave le afi servo, fetuutuunai theposition o le tagata lava ia soofaatasi voltage regulator mo carbon brush, faia le fua fua o le voltage e oo atu i le tulaga mautu. fa'agaioiga umi ma isi uiga, e fa'atuai le taimi, luga o le voltage, undervoltage puipuia galuega. e mafai ona faʻaaogaina lautele i le eletise lea e manaʻomia ai le voltage mautu, o se ituaiga o tuʻuina atu faʻamautu leleivoltage. Ia mautinoa o lau fa'agaioiga masani o masini eletise
